Supervised and Unsupervised Learning are two primary types of machine learning, differing mainly in how they process and learn from data.

Neural networks are a type of machine learning model inspired by the structure and function of the human brain. They are designed to recognize patterns and relationships in data through a process of learning.

Machine learning improves predictions in real-world data applications by learning from past data patterns and adapting to new information without being explicitly programmed for every scenario.

Here’s how it boosts prediction accuracy and usefulness:

1. Learns Patterns from Historical Data

ML models analyze large datasets to identify complex relationships (e.g., buying habits, fraud patterns) that humans might overlook.
Example: A retail model predicts future sales by learning seasonal trends, promotions, and customer preferences.

2. Handles Complex, Non-Linear Relationships

Traditional statistical methods often assume simple linear relationships.
ML can model non-linear patterns and interactions between many variables, improving prediction precision.

3. Continuously Improves Over Time

With online learning or regular retraining, models adapt to changes in behavior, market shifts, or new data trends.
Example: A spam filter gets better at blocking new types of phishing emails as it learns from fresh examples.

4. Reduces Human Bias in Predictions

Instead of relying solely on fixed rules, ML bases predictions on data evidence—though care must be taken to avoid bias in the training data.

5. Processes Massive Amounts of Data Quickly

ML can analyze millions of records in seconds, enabling faster decision-making in areas like stock trading, weather forecasting, and demand planning.
